■Note for the entry function (if equipped)
●Even when the electronic key is within the effective range (detection areas), the system may not operate properly in the following cases:
• The electronic key is too close to the window or outside door handle, near the
ground, or in a high place when the doors are locked or unlocked. • The electronic key is near the ground or in a high place, or too close to the rear
bumper center when the trunk is opened.
●Do not leave the electronic key on top of th e instrument panel or near the door pockets
when exiting the vehicle. Depending on the radio wave reception conditions, it may be
detected by the antenna outside the cabin an d the doors will become lockable from the outside, possibly trapping the electronic key inside the vehicle.
●As long as the electronic key is within the effective range, the doors may be locked or
unlocked by anyone. However, only the door s detecting the electronic key can be used to unlock the vehicle.
●The doors may unlock or lock if a large amou nt of water splashes on the door handle,
such as in the rain or in a car wash, when t he electronic key is within the effective range. (The doors will automatically be locked af ter approximately 30 seconds if the doors
are not opened and closed.)
●If the wireless remote control is used to lo ck the doors when the electronic key is near the vehicle, there is a possibility that the d oor may not be unlocked by the entry func-
tion. (Use the wireless remote control to unlock the doors.)
●Touching the door lock or unlock sensor while wearing gloves may prevent lock or unlock operation.
●If the door handle becomes wet while the el ectronic key is within the effective range,
the door may lock and unlock repeatedly. In this case, follow the following correction
procedures to wash the vehicle:
• Place the electronic key in a location 2 m (6 ft.) or more away from the vehicle. (Take
care to ensure that the key is not stolen.)
• Set the electronic key to battery-saving mode to disable the smart entry & start sys- tem. ( P. 158)
●If the electronic key is inside the vehicle and a door handle becomes wet during a car wash, a message may be shown on the mult i-information display and a buzzer will
sound outside the vehicle. To turn off the alarm, lock all the doors.
●The lock sensor may not work properly if it comes into contact with ice, snow, mud, etc. Clean the lock sensor and attempt to operate it again, or use the lock sensor on the
lower part of the door handle.
●A sudden handle operation or a handle operation immediately after entering the effec- tive range may prevent the doors from bein g unlocked. Touch the door unlock sensor
and check that the doors are unlocked before pulling the door handle again.
●Unlocking the vehicle may take more time if another electronic key is within the effec- tive range.
